2 Claims.

This invention relates to wrist watches, the object being to provide a construction that will protect the watch from the danger of injury by water. By my invention the watch may be safely worn in the most severe rain storms, and, indeed,

may actually be worn with safety while the wearer is in bathing. 1

In the accompanying drawing- Fig. l is a front view;

Fig. 2 is a side view;

Fig. 3 is a rear view with the rear protective covering removed;

Fig. 4 is a cross-section the watch in edge elevation;

Fig. 5 is a rear view similar a modification;

Fig. 6 is an edge of Fig. 5;

Fig. 7 is a view similar to Fig. 3 showing another modification Fig. 8 is a fragmentary 1 represents a watch. In the form shown in Figs. 1 to 4, 2 represents a housing having a cavity therein adapted to receive the watch 1. The front of the housing has a window opening for the reception of a glass or crystal 3. When the glass 3 is inserted, the surrounding edge of the housing is preferably burnished in against the edge of the crystal so as to form a water-tight joint. Waterproof cement might be employed, if desired. The case is provided with a cover 4 which is removable so that the watch l'may be inserted or removed. The cover4 has a flange 4 that fits friction-tight with accuracy into the surrounding wall of the housing 2 so as to form.

- a water-tight Joint. If the opening into the housing for the insertion and removal of the watch is round, as in Figs. 5 and 6, the edge could be threaded to receive a threaded flange 4 on the removable cover. 5-5 are bars at opposite sides of the housing 2, to which bars the ends of a wrist strap 6 may be secured so that the device may be strapped to the arm of the user. The cover is so designed that when it is closed it will engage some-portions of the watch- 1 so as to hold it in place. In the drawing, the flange 4* is of such depth as to engage the wrist strap lugs 7'7 on the watch 1, thereby preventing the watch from shaking about in the holder. The lugs 7-7 act as spaced abutments at opposite sides of the watch case, all of which are arranged to bear endwise against the adjacent wall of the housing'2, so as to properly center the watch of the holder with to Fig. 3, showing view of parts of Fig. '7.

therein as well as take the thrust of the flange 4 when the latter crowds said watch against the flange around the edge of the window opening, as shown in Fig. 4. It will be noted that the housing not only covers and protects the case of the watch 1, out it also covers and protects the winding stem 1 thereof, and since no water can enter the housing it will be seen that the watch. is fully protected. against that element.

In Figs, 5 and 6 I have shown the housing 2 as round with a round removable cover having the aforesaid threaded flange 4 The cover has a flange or outergnarginal portion extending substantially to the edge of the housing so. that it may be readily gripped so as to screw and unscrew the sameirom the housing. The housing itself is deep enough to completely house the watch and the cover may be flat and simply act as a closure.

In Figs. 7 and 8, the removable cover is located at the edge of the housing 2 instead of at the front or back. The cover is indicated at 4, and when in place as in Fig. '7, makes a water-tight joint.

I claim:

1. A wrist watch comprising a watch proper, a housing having a water-tight window through which the face of the watch is visible, centering lugs at opposite sides of the case of the watch for engaging the side walls of said housing, a removable cover for said housing to permit" the insertion and removal of said watch, a portion of said cover engaging said lugs to crowd said watch case against that portion of the housing around said window, and means on said housing for connecting a strap thereto.

2. A wrist watch comprising a watch proper, a cup-shaped housing having a water-tight window through which the face of the watch is visible, said housing being of sufficient depth to completely hold the watch proper, a flat cover for said housing, said cover having a peripheral flange portion extending substantially to the edge of the housing and having a circumferential inwardly directed flange radially inwardly of the marginal edge of said cover and in screw threaded engagement with said housing, and bracelet attachment means secured to said housing with abutment shoulders on said watch for engagement by said circumferential flange.
